Hey everyone I have always wondered why I can't play SC2 in Ultra/Extreme without some lag and choppiness.


My computer specs:

CPU: AMD Phenom(tm) II X4 965 Processor (4 CPU) 3.4~ GHz
GPU: ATI Radeon HD 5700 Series
RAM: 8 gb
OS: Windows 7 64 bit

and on canyourunit.com it says I'm exceeding recommended.

Any help would be awesome!

Thanks!

Two things:

(1) Your rig is kind of low end.
(2) Even very powerful rigs don't do well with ultra in large battles (especially team games). That is because Blizzard only bothered to code the game to use 2 cores. So, for example, an i5 can only use half of its cores.

I play the game on a mix of high and ultra. Here are my system specs:

Well you can't run it in Ultra setting. You probably run it on mixed Mid High with 200/200 battle of 1v1. I have the pretty same rig as yours, and I run on Low to have nice FPS & nice response.

Ultra physics and effects can't be ran even by very good computer with a playable FPS, because of the CPU issue Salient mentionned.
Running the game on ultra without physics and effects maxed is doable though, and you should even get more or less the same FPS than on full low if you go ultra with the CPU options put on low if you have a decent GPU.

A 5750/5770 would struggle with 1080p+ ultra as well, especially in hots.

Well thanks a lot Salient! Rollin do you have any recommendations on graphics cards?

Uh well early game you're going to be limited by your graphics card on ultra, and lategame you're going to be limited by your cpu (regardless of settings), so my recommendation is to not play on ultra. I turn off most of the post processing anyway because it looks like shit.

The performance per Mhz of the Phenom II (and most other modern AMD cpus) is rather low. So for Ultra you would need mostly a better CPU. I would not recommend a AMD cpu here because of the issue mentioned. You need strong cores, rather than many.
A nice Intel i5 for example would do (at least in 1v1). For that, you would need a new motherboard as well though.

Yea sc2 will only max 1 core and load another to ~40% on a strong CPU, no performance difference just playing having 2 cores enabled vs 4 from what i could see (didn't bench it, but didn't seem big)

performance tiers between like stock phenom II, stock sandy/ivy/haswell and high oc on intel CPU are pretty massive. Once you've got oc'd i5, performance stops going up though (as hyperthreading doesn't help you for solely running sc2 and i7 offers nothing else - then the 6 core CPU's regress in performance on each individual core in order to run 6)

If you're looking to boost minimum FPS or FPS in fights or just later in the game with lots of units, CPU is 100% the way to go, if your FPS at certain settings are unsatisfactory with like 6 workers and nothing else happening then you maybe want a GPU upgrade. I think if you were to upgrade GPU though, you might just see the same FPS on same settings when FPS starts to drop because you'd likely be CPU limited. My friend on an e8400 (core 2 duo @3ghz, forgot the arch name) and a 5770 did some quick benchmarks for me and showed pretty much identical FPS on min vs max settings in a high supply 2v2 game, the big thing to do when you're talking about raising graphical settings is to raise other stuff, but NOT physics/reflections/effects, and if your GPU is half decent with a CPU that's not amazing you might find FPS hardly changes where it matters

Honestly, the best gift blizzard could give would be rewrite of sc2 engine, changed pathing, scalability onto more than one core with dx11 api. That would improve so much for so many people

Anything changed in that department?

No, we just have some CPU's with faster core & RAM performance
